Overview
Grease traps (also called grease interceptors) protect drains and sewers by capturing fats, oils and grease before they enter the wastewater system. For small kitchens you want a unit that balances capacity with available under‑sink space and the peak flow of your fixtures.
This comparison looks at three carbon‑steel VEVOR models in increasing capacities. Each uses a side‑inlet, under‑sink layout and shares common inlet/outlet sizing, so the main differences are weight, internal volume and flow rate.
Choosing the right size depends on how many sinks or appliances drain into the trap, how busy service periods are and local regulations. A too‑small trap will need frequent emptying and risks non‑compliance; a too‑large unit may be awkward to fit or unnecessarily costly.
Read the short cards below for a concise summary, then use the buying guide to match capacity and flow to your kitchen layout and cleaning routine.

Detailed reviews
#1 VEVOR Commercial Grease Trap, 40 LBS Grease Interceptor, Side Inlet Interceptor, Under Sink Carbon Steel Grease Trap, 15.2 GPM Waste Water Oil-water Separator, for Restaurant Canteen Home Kitchen
This VEVOR 40 lb grease interceptor is an under‑sink, side‑inlet unit built from Q235 carbon steel. It’s designed for commercial kitchens and can handle a relatively high flow rate for its class, which helps during peak service. The unit’s heavier construction and larger internal volume mean longer intervals between emptying compared with smaller traps, but you should still plan regular maintenance. Connections use a common 48 mm inlet/outlet size, making it compatible with many existing plumbing setups, while the reliable sealing design aims to limit odour escape. Check local requirements for interceptor sizing and ensure the physical dimensions suit your available space before buying.
Key features
- Primary material: Q235 carbon steel
- Capacity: 40 lb grease interception
- Flow rate: 15.23 GPM (approx.)
- Inlet/outlet size: 1.89 in / 48 mm
- Under‑sink, side inlet configuration
- Product dimensions: 650 x 450 x 460 mm
#2 VEVOR Commercial Grease Trap, 30 LBS Grease Interceptor, Side Inlet Interceptor, Under Sink Carbon Steel Grease Trap, 10.8 GPM Waste Water Oil-water Separator, for Restaurant Canteen Home Kitchen
The VEVOR 30 lb grease trap is a mid‑sized under‑sink interceptor built from Q235 carbon steel. It offers a moderate flow rate suitable for small commercial kitchens, cafés or satellite food prep areas where the workload is steady but not extreme. Dimensions are smaller than the 40 lb model so it’s easier to fit under many sinks while still providing sensible grease holding capacity. It shares the same 48 mm inlet/outlet sizing, which simplifies plumbing connections. As with any grease interceptor, regular emptying and cleaning are needed to keep performance and compliance on track.
Key features
- Primary material: Q235 carbon steel
- Capacity: 30 lb grease interception
- Flow rate: 10.81 GPM (approx.)
- Inlet/outlet size: 1.89 in / 48 mm
- Under‑sink, side inlet layout
- Product dimensions: 600 x 400 x 420 mm
#3 VEVOR Commercial Grease Trap, 8 LBS Grease Interceptor, Side Inlet Interceptor, Under Sink Carbon Steel Grease Trap, 4.6 GPM Waste Water Oil-water Separator, for Restaurant Canteen Home Kitchen
The VEVOR 8 lb grease interceptor is the most compact option in this group. Its smaller internal volume and lower flow rate make it suitable for very small kitchens, mobile catering units or single‑sink dishwashing stations where space is limited and grease production is modest. The unit is lighter and easier to manoeuvre, but it will need more frequent emptying in anything beyond low‑usage scenarios. It uses the same 48 mm inlet/outlet sizing as the larger models, which keeps plumbing consistent across sizes. Make sure the 4.64 GPM figure meets your peak flow needs before choosing this model.
Key features
- Primary material: Q235 carbon steel
- Capacity: 8 lb grease interception
- Flow rate: 4.64 GPM (approx.)
- Inlet/outlet size: 1.89 in / 48 mm
- Under‑sink, side inlet configuration
- Product dimensions: 305 x 290 x 390 mm
Buying guide
1) Check local regulations: many councils set minimum capacities and maintenance intervals for commercial kitchens. 2) Estimate peak flow: add up the fixtures that will discharge to the trap (sinks, dishwashers). Match that to the trap’s flow rate (GPM/LPM). 3) Choose capacity by workload: busier kitchens need larger interceptors to reduce emptying frequency. 4) Measure under‑sink space: compare unit dimensions and weight with the space available and access for maintenance. 5) Consider material and seals: carbon steel is common and durable, but ensure lids and gaskets provide a good seal for odour control. 6) Plan maintenance: factor in how easy the lid and internal baffles are to access for scraping and cleaning, and whether you need a service contract.
FAQs
How often should a commercial grease trap be emptied?
Frequency depends on capacity and kitchen workload. A rule of thumb is before grease reaches 25% of the unit’s liquid depth, but check local rules and inspect regularly — busier kitchens may need weekly emptying while quieter sites can do it monthly.
Can I install a grease trap myself?
Basic plumbing skills may suffice for small under‑sink units, but installation must meet local regulations. For compliance, particularly in commercial settings, use a qualified plumber or follow council guidance.
Does material matter?
Yes. Carbon steel is durable and common for commercial traps, but ensure coatings, gaskets and lids are corrosion‑resistant and that the unit is easy to clean to prevent odour and blockages.
Our recommended choice
For most small commercial kitchens that need a balance of capacity and under‑sink fit, the 40 lb VEVOR interceptor is the best starting point. It offers a higher flow rate and capacity that will reduce emptying frequency without being excessively large for many back‑of‑house spaces.
